+Sometimes you may want your sidebar's position to stay fixed when other parts of your page scrolls. This can be done via the `sticky` option of the sidebar in the theme's `_config.yml`. You can set any of the sidebar or even both of them to `sticky`.
+
+```yaml
+sidebar:
+    left:
+        sticky: false
+    right:
+        sticky: true
+```
+<!-- more -->
+<div style="height:2000px;background:#fafafa;color:#777;text-align:center;">
+<br>
+<p>This is some really long content.</p>
+</div>
